Configuration manual

• For PVLAN, if the IP address is configured for the primary VLAN, L3 routing is enabled.
NOTE: If the CAM is full, do not enable peer-routing.
NOTE: The peer routing and peer-routing-timeout is applicable for both IPv6/ IPv4.
Configuring VLT Unicast
To enable and configure VLT unicast, follow these steps.
1. Enable VLT on a switch, then configure a VLT domain and enter VLT-domain configuration mode.
CONFIGURATION mode
vlt domain domain-id
2. Enable peer-routing.
VLT DOMAIN mode
peer-routing
3. Configure the peer-routing timeout.
VLT DOMAIN mode
peer-routing—timeout value
value: Specify a value (in seconds) from 1 to 65535.
Non-VLT ARP Sync
In the Dell Networking OS version 9.2(0.0), ARP entries (including ND entries) learned on other ports are
synced with the VLT peer to support station move scenarios.
Prior to Dell Networking OS version 9.2.(0.0), only ARP entries learned on VLT ports were synced
between peers.
Additionally, ARP entries resulting from station movements from VLT to non-VLT ports or to different
non-VLT ports are learned on the non-VLT port and synced with the peer node. The peer node is
updated to use the new non-VLT port.
NOTE: ARP entries learned on non-VLT, non-spanned VLANs are not synced with VLT peers.
RSTP Configuration
RSTP is supported in a VLT domain.
Before you configure VLT on peer switches, configure RSTP in the network. RSTP is required for initial
loop prevention during the VLT startup phase. You may also use RSTP for loop prevention in the network
outside of the VLT port channel. For information about how to configure RSTP, Rapid Spanning Tree
Protocol (RSTP).
Run RSTP on both VLT peer switches. The primary VLT peer controls the RSTP states, such as forwarding
and blocking, on both the primary and secondary peers. Dell Networking recommends configuring the
primary VLT peer as the RSTP primary root device and configuring the secondary VLT peer as the RSTP
secondary root device.
